vMy invention has for its object to provide a highly eicient welding table for holding.rv f f aligning andv leveling parts of. different..

shapes', sizes, and lengths which ,a Welder vmust setv for welding so that the work may.

he quicklyand'efiiciently done.

The hand wheel-equipped nut 16 is arranged to impi'ng'ea'gainst the Guadrant 15I and frictionally ,clamp vsaid `quadrant onto the post 8 in a true horizontal position or Vinl dierent tilted positions.. *Thefqnad-l rant 15 is attached tothe table top in the same manner that the, quadrant-14@ lis. attached thereto'.V Ohviouslyyby loosening the desired degree. and y'this tilting feature perl mits a -joloto bequicklv leveled. thuseliminating impractical methods of blocking up. Y The talole top 6 is provided at its hack, right nut 16. the table top 6 mav be tilted toany .and left-handiedges with depending anges,

the latter two of which areindicated bythe numerals' `18 andy 19, respectively. Said tabletop 6 is alsoprovided'withv a 'depending flange 20'which' extends parallel to the further reinforce-d by azmultiplicity of cross ribs l21 which givev said" tabler topl the required strength. f v

' Formed in the front longitudinal edge portionjof the `table ytop, 691s'fafV-sha'pedy groove 22 which extends' the'iull' Vilengtlro-iv `said tabletop, and which tabletop;` at suh- 'i "flange 19 and is laterally lspaced inward therefrom. In addition tothe .flanges above noted; thetahle top, on its underside; is

-stantiallythe longitudinal,center'of' the groove 22, is providedwith a flame passageway 23 which extends transversely into said groove. This V-shaped groove 22 is especially adapted! forholding rods, shafts and the like, of different lengths andv diameters, and the diverging walls thereof will hold parts to be welded properly aligned. Extra j long rods, shafts or other parts in the groove 22 are further held by a supporting block 24 mounted on a rod secured to the flange 19, through which it projectsrearward of the groove 22, by opposing nuts 26.7 This rod 25eXtends parallel to the groove V22 and' is r'pi" vid'e"d' with a crank portion` 27. As

shown, the supporting block 24, at its rear end portion, is" provided with a bossed hole 28 through which the rod 25i projects', and which supporting block is secured thereto by a thumb screw 29. In the upper edge ofthe supporting block 24 is a relatively wide notchv 30.

Obviously, by loosening the thunibgscrew f 29, the supporting block 24 may be adjusted lnn'gitudiiia'llyon the rod toward' and from the' groove 22 or swung` in a vertical plane, and byloo'sening one ofthe nuts 26, the rod 25V may be turned in the flange 19V to cause itscrank portion 27 to raise or lower the supporting block 2'4 and' impart an endwise 4sets' that vary in length.

plurality of laterally spaced stub shafts 32 of different diameters are mounted in 'aligned bores in the flanges 19 and 2O rfor endwise slid-ing movement. Each 'stub shaft 32 is provi-ded with a cotter pin 33 arranged toA engage the flanges 19 'and 20 to limitV the end'wise movement of said stuby shafts. The purpose' of these stub shafts 32 is to support gears, pulleys, rings and the like, and Ythey are 'especially well adapted to support gears while weldingV teeth thereon' for the reason that said shaftsfcan be set in true horizontal position by tilting the tabletop 6, and said `gears rotated tobring the work at thetopv of said'gears. When the shaftsl32 are in their innermost positions, their outer ends are substantiallyv flush with the outerface ofthe Harige 19so1as'to` out Vofthe way. Secured tothe fla-nge 18 is a'plurality'of hooks 34 for supporting the linksof a chain or the like.

Ai head stock' 35 havinig a lixed center 36,

v`and a tail stock 37 having an adjustable center 38 are adjustahly and removably supported onv the table-top 6. i These head and tail stocks 35 and 37, respectively, are'provided with dove-tail ribs 39 slidably mounted in a correspondingly formed groove 40 in the table top 6, and which groove extends parallel to the groove 22. Nut-equipped bolts 41, which extend through bores in the bases of said head'an-d tail stocks-and the groove 40, are provided for securing said head and taii stocks to the table top 6 in different adjustments. The attachment comprising the head and tail' stock-s takes the place of a lathe, for the purpose of Ytrying out Jand straightening' crank shafts, axle shafts, driving shafts, cam shafts or any' other work to bevswung on centers. y y

Tn' the table top 6 are a multiplicity of differently shaped holes 42 in' which may be bent fiat, round, square, angular or' any other shaped parts. Afork-like welding torch tip 43 is removably secured at different positions on the table top 6 by providing'rthe same with a reduced stem' adapted toghe' `in i sert'ed in any one of a plurality of holes 44 in said table top.Y Atthe yfront right-hand corner of the tabletop 6 isa eup-likedepression 45 for vreceiving babbitt as the saine is melted from bearings.

The back and one of the A'si-des ofthe table top 6 are planed true at right angles to' each other so as to' be used as a square in truing up work. f' 'f An aligning block 46 is mounted in one of the longitudinal openings 4:2v liust forward of the head and tail'v stocks and is provided with a depending socket in whichthe upper end of an upright combined supporting and' This 'feed screw feed screw 47 is mounted. 47 has screw-threaded engagement with intermediate portions of a U-shap'ed supporting bracket 48, and Von its lower end is a hand piece 49 by whichV said screw may be turned. The armsof the supporting bracket 48 extend outward of the two ribs 18, at the respective opening 42, andV are detachably secured thereto by opposing set screws 50. To prevent the aligning block 46 from turning on its feed screw 47 orwith said screw, the same isf'provided with a depending stern 51 which. extends through an aperture in the intermediate portion of the supiio porting bracket 48 with freedom for'endwise movement.

By the use of this aligning block .46, a part supported thereon may be aligned with a part supported onrthe table top 6 and thus held while beingwelded. To hold apart on with a transverse groove 52.

In Fig. 7 is shown another form -of `alignling block, -indicated by the numeral 53, and A'its depending stem by the numeral 54. This A Yfor holding a part held thereon.
